prosit, If unit can be opened, I recommend you visually inspect the main power supply printed circuit board for "bad" electrolytic filter capacitors that may be faulty and failed prematurely! Lots of DIY videos at YOUTUBE that you should view before doing a "teardown" !!! Remember THIS!!! You MUST document your teardown with video or digital stills so before disconnecting any connectors to the board so you can put unit back together exactly as it was before you started any board repair work!! e.g. replacement of filter capacitors, fuses, resistors, and solder joint inspection of through-hole and or surface mounted active and passive components. DO YOUR WEB RESEARCH OF YOUTUBE VIDEOS FIRST!!!! Good luck guy. Keep us tech's informed of your progress by doing additional posts (comments) here on fixya. 12fixlouie
